Epsilon™ PRO is a thixotropic epoxy coating that self-thickens for brushing onto a variety of surfaces. Compared to original Epsilon™, Epsilon™ PRO offers a longer working time and cured epoxy is semi-rigid, offering better impact resistance. Mix ratio for Epsilon™ PRO is 2A:1B by volume (100A:44B by weight). A gram scale is not needed to use this product. Applied in thin layers, mixed material holds a vertical surface without sagging or slumping. Material wets out uniformly over different surfaces. Pot life is 22 minutes, with a re-coat time of 3 hours. All layers should be allowed to cure for 16 hours at 73° F / 23° C and can be accelerated with mild heat. Epsilon™ PRO is clear and can be easily colored using a variety of colorants. Available in trial (1.4 lb.) sets, gallon (11.5 lb.) sets, and 5 gallon (64.8 lb) sets.
